I'roY AEROPLANE.

To ZZ whom t may concern Be it known that I, HARRY M. SMURR, a citizen of the United States, residing at Armona, in the county of Kings and State of California, have invented certain new and useful Improvements in Toy Aeroplanes, of which the following is a specifica.- tion.

rl`his invention relates to a toy aeroplane which is capable of being manually propelled over the ground.

An important object of the invention 1s the provision of a toy aeroplane of the conventional aeroplane construction, which is capable of being manually propelled over -the ground. and in which the propeller blade is made to revolve.

A further object of the invention is the provision of a toy aeroplane of the above described character having means thereon to make a noise simulatingthe explosions of an aeroplane engine.

A further object of the invention is the provision of a device of the above character being so adjustable as to permit persons of varying sizes to ropel the' same.

In the accompanying drawings forming a part of this specification and in which like reference characters designate like parts throughout the same:

Figure 1 is a side elevation of the toy aeroplane.

Fig. 2 is a plan view of the toy aeropla-ne.

Fig. 3 is a front elevation ofthe toy aeroplane.

Fig. 4 is a side elevation partly in section of the toy aeroplane.

Fig. 5 is a fragmentary sectional view showing the means employed for making a noise similar to the explosions of an aeroplane engine.

Fig. 6 is a front sectional view of the supporting means.

F ig. T is a perspective view of the empennage or rudder of the toy aeroplane.

ln the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the letter A represents the fuselage having wings B thereon,

to which an empennage or rudder C is pivotally attached. The fuselage A rotatably carries the propeller blade D and has a landing gear constructed thereon comprising an under frame E and supporting wheel F to which is attached an adjustable handle' G for manually propelling the aeroplane.

The fuselage A is preferably constructed of hard wood and is of conventional aeroplane construction, being gradually tapered from the front toward the rear. A longifuselage A and communicates through an aperture 11 with the outside and beneath the fuselage.

The aeroplane is preferably of bilplane construction, and has a bottom wing 12 mounted upon the forward part of the fuselage A. and overhanging which is the wing 13 supported by struts 14 to the lower plane 12 and which planeis slightly longer on each end than the lower plane 12. The empennage or rudder C is pivot-ally mounted upon the rear of the fuselage A by a pin 1,5 and comprises a horizontally pointed portion 16 and the vertical rudder portion 17. The portion 17 is provided with slits 18 stamped or cut therein and which are provided for the purpose of receiving the in 15.

T e propeller D is preferably of the screw type having blades 19 and 20 thereon and which is mounted upon a shaft 2l projecting Ywithin the fuselage and bearing therein, and

which has a portion thereof projecting within the longitudinal recess 10 of the fuselage. A plate 22 is provided upon the nose of the fuselage and maintained in position by rivets 23 for the purpose of maintaining the shaft within the fuselage or body A.

The under frame .E of the toy aeroplane is preferably composed of the two longitudinal members 24 and y25 which are rigidly connected to the rear of the fuselage by the braces 26 and 27 respectively, and which are connected to the forward end 'of the fuselage A by braces 28 and 29 respectively, rigidly attached to the wing 12 by rivets 30 or the like. A bolt 31 is provided through the forward part of the longitudinal meinbers 24 and 25 andy the lower part of the braces 2S and 29, and which acts as an axle for rotatably supporting the wheel F. The wheel l is preferably of disk construction having a, solid tire 32 thereon, and which has preferably integral therewith a grooved hub 33 and a toothed hub 34 disposed upon the side opposite the grooved hub 33. If it is preferred the hub sections and 34 can be made separate from the Wheel structure F and rigidly assembled thereto during the assemblage of the device. A flexible cable 35 is provided which engages the groove 3G of the grooved hub 33 and which is projected upwardly in the apert-ure 11 in the fuselage A and placed about the propeller shaft 21 for turning the propeller upon rotation of the Wheel F. The longitudinal member 25 of the undercarriage E has a portion thereof adjacent its connection to the bolt 31 cut aivay and is provided with the groove 37 adapted for the reception of an end 38 of a flexible strip 39, of sufficient length to engage the teeth 40 of the toothed Wheel 34.

The handle G is provided with the hand engaging portion 41 having the aperture 42 therein adapted for reception of a string, rope, stick or the like, and which also has an end 42 thereof pivotally `connected to the longitudinal members 24 and 25 by a bolt 43 which also engages'the depending ends of the braces 26 and 27.

In operation, the handle Gr can be adjusted upon the bolt 43 in order that the end of the handle engaging portion 41 can be adjusted to the required height, and is .then tightened in its place `by rotationor tightening of the nut 44 upon the bolt 43. In its downmost position the portion 42 of the handle G abuts against a bolt 45, and

is prevented from any further downwardv movement. As the toy aeroplane is manually propelled over the ground, the rotation of wheel F will also rotate the grooved hub 33 and toothed hub 34. As the toothed hub 34 rotates the teeth 40 will push against the flexible strip 39 unt-il the strip comes in contact with the outwardly flaring face 47 of the groove 37, thus bending the strip and putting it under pressure and vvhen this tooth 40 releases the flexible stick 39 it will fly back into its original position and strike against the succeeding tooth 40, thus making noises in rapid succession which simulate the explosion of an aeroplane engine. As the hub 33 alsorevolves with the Wheel F it will cause the flexible cable 35 to rotate the shaft 21 which is transmitted to the propeller D and consequently causes the propeller D to rotate While the Wheel F is rotating and with a great many more revolutions in a certain period of time than the Wheel. Since the empennage C is pivotally mounted upon the rear of the fuselage the rudder member 17 Will because of the cont simulating tact with the air and the resistance thereof plane is moving.

It is to be understod that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape` size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:
